<h1>Beta/RC Releases and Development snapshots (unstable) <img class="logo" src="/media/img/about/press/elephant.png" alt="PostgreSQL Elephant Logo" /></h1>

<p>
Beta and Release Candidate packages are built prior to the release of
new major versions of PostgreSQL. They are not built continually.
</p>

<p>
Development snapshots are built from the latest source code and
beta/rc versions that the developers are working on.
These are 'bleeding edge' versions of PostgreSQL and
<span class="text-danger font-weight-bold">should not be used in production systems</span>
as they have had little or no testing or quality control.
</p>

<p>
The latest development version of the documentation is also
<a href="/docs/devel/index.html">available online</a>.
</p>

<h2>Source code</h2>

<p>
Beta and Release Candidate tarballs are <a href="/ftp/source/">made available
alongside</a> the release tarballs during the final phases of the development
cycle of new major versions of PostgreSQL.
</p>

<p>
Source code tarballs are built automatically every night on the official
PostgreSQL development server. The
<a href="/ftp/snapshot/dev/">development snapshot</a> is taken from the
head of the git repository, and includes the new features being worked
on for the next release. There are also "branch tip" snapshots built from
all supported <a href="/ftp/snapshot/">stable branches</a>, which contains
all bugfixes that are scheduled for the next release.
</p>

<h2>Installers</h2>
<p>
Installers for Windows and Mac are available <a
href="https://www.enterprisedb.com/products-services-training/pgdevdownload">
here</a> (offsite link). These installers also include pgAdmin and are
published by EDB.
</p>

<h2>Red Hat, CentOS, Fedora and Scientific Linux</h2>
<p>
RPMs for Red Hat, CentOS, Fedora and Scientific Linux are available from the
<a href="https://yum.postgresql.org/">PostgreSQL Yum repository</a>.
</p>
<p>
To setup the repository for these versions, follow the same instructions
as for the <a href="/download/linux/redhat/">normal</a> yum repository on these
platforms.
</p>

<p>
Typically only Beta and Release Candidate packages are available in the
Yum repository.
</p>

<h2>Debian, Ubuntu Linux</h2>
<p>
DEBs for Debian and Ubuntu are available from the
<a href="https://apt.postgresql.org">PostgreSQL APT Repository</a>
repository.
</p>
<p>
To setup the repository for these distributions, follow the instructions
on <a href="/download/linux/debian/">Linux Downloads (Debian)</a> or <a href="/download/linux/ubuntu/">Linux Downloads (Ubuntu)</a>.
</p>
<p>
Typically only Beta and Release Candidate packages are available in
the PostgreSQL APT repository.
